Single row cylindrical roller bearings are manufactured in several different designs, the main difference being in the configuration of the flanges. The most popular are the NU, N, NJ and NUP designs. Cylindrical roller bearings can accommodate heavy radial loads and high speeds. Some with different structure of ribs can also bear one way or two way axial loads. NN and NNU double row cylindrical roller bearings have a low cross section, high load carrying capacity and high stiffness, therefore it is mostly used in machine tool spindle stands. FC, FCD, FCDP four row cylindrical roller bearings with large capacity of radial load, mostly applied in rolling mill and heavy machinery.
The inner ring has two integral flanges and the outer ring is without flanges. Axial displacement of the shaft with respect to the housing can be accommodated in both directions within the bearing itself. The bearings are therefore used as non-locating bearings.
2. NU type:
The outer ring of bearings of the NU design has two integral flanges and the inner ring is without flanges. Axial displacement of the shaft with respect to the housing can be accommodated in both directions within the bearing itself.
The outer ring has two integral flanges and the inner ring one integral flange. The bearings are therefore suitable for the axial location of a shaft in one direction.
4. NF type:
The outer ring has one integral flange and the inner ring two integral flanges.
The outer ring has two integral flanges and the inner ring one integral flange and one non-integral flange in the form of a loose flange ring. The bearings can be used as locating bearings, i.e. they can provide axial location for a shaft in both directions.
6. RN type:
No outer ring and the inner ring two integral flanges.
NN type bearing without ribs on outer ring,there is a wall in the midel of between both sides of inner ring. It can make shaft relative bearing between the axial displacement generated in both directions.
